Abstract

An ejector-type gas nozzle 17 including a liquid nozzle and a gas nozzle is used. Raw material water A in ozone reaction tank 1 is pumped and pressurized by pump 19 to use it circulatingly as water jet A of the ejector gas nozzle 17. The liquid nozzle of ejector-type gas nozzle 17 introduces the water jet A into the raw material water A in the ozone reaction tank 1. Ozone gas is sucked by negative pressure to be generated along the stream of water jet A so that it is injected into the raw material water A from the gas nozzle of ejector-type gas nozzle 17 as fine gas bubbles. A high concentration ozone water solution is produced by dissolving ozone into the raw material water A due to the gas-liquid reaction between the ozone fine gas bubbles and the raw material water A.
